Testing the WAN Interfaces
The WAN interface can be tested using ping as described in the previous section. If the ping is not successful,
check the routing table to see if a route to the destination exists (INFO =>SHOW ROUTING TABLE). The
menu items INFO =>SHOW STATISTICS =>SWAN and INFO =>SHOW STATUS =>SWAN may also provide
useful information.
If the router does not seem to be working properly, and none of the above advice has located the problem, the
hardware interfaces should be tested. This will determine if the problem is hardware, software, or configuration
related.
This test will be between the two SWAN interfaces.
1 Connect the cable labeled “cross” between the two interfaces to be tested.
2 Choose DEBUG =>HARDWARE TESTS =>NEW RUN-IN from the menu. Test options for each interface
are shown. Choose Yes for the two SWAN RSV interfaces and No for all other tests. Let the test run for a
while. Pressing “G” will show the General Statistics Table (Figure A.3).

FIGURE A.3 GENERAL STATISTICS TABLE.
• The first three columns show which interfaces are being tested.
• The H column shows which board is master and which is slave.
• The LP column indicates how many test loops have been completed.
• The E%% column shows how many errors per 1000 packets have occurred.
